Frozen Embryo Transfer (FET)

Frozen Embryo Transfer (FET) is a vital component of modern assisted reproductive technology (ART). It involves thawing and transferring previously frozen embryos into the uterus, offering a flexible and effective option for those undergoing in vitro fertilisation (IVF). FET is widely used to increase the chances of conception while reducing the physical and emotional strain of repeated ovarian stimulation. 

At Dr. Kamaraj Hospital and Aakash Fertility Centre, we specialise in advanced FET procedures, providing personalised care to help couples achieve their dream of parenthood.

What is a Frozen Embryo Transfer?

A frozen embryo transfer is a process where embryos created during a previous IVF cycle are frozen and stored for future use. When a couple decides to proceed with FET, the embryos are carefully thawed and transferred into the uterus during an optimal time in the menstrual cycle to enhance the likelihood of implantation.

Freezing embryos allows flexibility for patients and provides opportunities for additional pregnancy attempts without requiring another egg retrieval procedure.

Why Choose Frozen Embryo Transfer?

FET offers several advantages, making it an increasingly popular choice in fertility treatments:

  • Higher Success Rates: Improved freezing techniques, such as vitrification, preserve embryo viability, leading to comparable or better success rates than fresh embryo transfers.
  • Reduced Stress on the Body: Eliminating the need for ovarian stimulation and egg retrieval during FET cycles decreases physical strain and recovery time.
  • Better Uterine Preparation: Synchronizing the uterine environment with the embryo transfer through hormonal therapy or natural cycle monitoring enhances implantation success.
  • Options for Genetic Testing: Freezing embryos allows time for preimplantation genetic testing (PGT) to ensure the transfer of healthy embryos.

The Frozen Embryo Transfer Procedure

The Frozen Embryo Transfer Procedure

The FET process typically involves the following steps:

  1. Initial Consultation: A detailed discussion with a fertility specialist to review medical history, discuss embryo quality, and plan the transfer.
  2. Uterine Preparation: Depending on the approach, this may involve:
    • Hormone Replacement Therapy (HRT): Medications like estrogen and progesterone prepare the uterine lining.
    • Natural Cycle Monitoring: Tracking ovulation in women with regular cycles to time the transfer.
  3. Embryo Thawing: Frozen embryos are thawed in a specialized lab with utmost care to preserve their viability.
  4. Embryo Transfer: Using ultrasound guidance, the embryo is placed into the uterus with a thin catheter. This is a quick and minimally invasive procedure.

Post-Transfer Monitoring: A pregnancy test is conducted approximately 10-14 days after the transfer to confirm success.

Success Rates and Factors Affecting FET

Frozen embryo transfers have consistently shown high success rates, comparable to or exceeding fresh embryo transfers, thanks to advanced freezing techniques. Factors influencing the success of FET include:

  • Embryo Quality: High-quality embryos increase the likelihood of successful implantation.
  • Uterine Receptivity: A properly prepared uterine lining enhances the chances of success.
  • Maternal Age: Younger patients typically experience higher success rates.
  • Lifestyle Factors: Maintaining a healthy lifestyle improves overall fertility outcomes.

FAQ

What is the difference between fresh and frozen embryo transfers?
Embryos are frozen using vitrification, a rapid freezing process that minimizes ice crystal formation and preserves embryo quality.
Only embryos that meet certain quality criteria are suitable for freezing to ensure high survival rates during thawing.

Infertility can be treated through lifestyle changes, medications and surgical procedures like varicocelectomy and microsurgical testicular sperm extraction and assisted reproductive technologies (ART) such as in vitro fertilization (IVF) and intrauterine insemination (IUI).

Embryos can remain frozen for several years without affecting their quality or viability.
Success rates vary based on factors like embryo quality and maternal age but are often comparable to fresh transfers.
